Kiribati's population was 103,058 in 2010. The vast majority (>90%) of people inhabit the Gilbert Islands, with more than 33% populating an area of about 16 km2 (6.2 sq mi) on South Tarawa. Until recently, the people of Kiribati mostly lived in villages with populations between 50 and 3,000 on the outer islands.
Kiribati, officially the Republic of Kiribati, is an island nation located in the central tropical Pacific Ocean. It is composed of 32 atolls and one raised coral island, dispersed over 3.5 million square kilometres, (1,351,000 square miles) straddling the equator, and bordering the International Date Line at its easternmost point.
There are a total of 21 inhabited islands in Kiribati. Kiribati is divided into three island groups, including a group that unites the Line Islands and the Phoenix Islands (ministry at London, Kiritimati) Island. The groups have no administrative function.
